John E. Davis Software


I have been involved in the free/open software movement for many years, long before it was fashionable. I have no strong philosophical or religious feelings about open software; my view is purely pragmatic: Since I take from the open source community, I try to give back to it.

Some of my contributions to the open software world include:

  • jed, a scriptable, multi-platform text editor.
  • S-Lang, a programmer's library that includes an array-based scripting language with a C-like syntax.
  • slrn, a powerful threaded newsreader for Unix, VMS, OS/2, and Win32 systems.
  • most, a more/less style paging program that supports multiple windows and scrolls left/right.
Follow the appropriate links for more information about these programs.

You might find the following links to also be of interest:

  • Technical Memos: Some memos that I have written that may be of interest.
  • Complex Domain Coloring: You don't need to be a mathematician to see how beautiful complex numbers are. See for yourself!
  • SLxfig: This package may be used to produce production-quality plots, drawings, posters, etc.
  • Antennas: Some antennas that I have designed for the digital television, MURS (unlicensed), amateur 2-meter (VHF) and 70 cm (UHF) bands.
  • thermochron: Here you will find some plots of the temperatures around my home measured using thermochron ibuttons.
